Yes it is - by definition, a parallelogram is described as having opposite sides and angles equal. A square is a 'special' type of parallelogram.
A parallelogram can be a square, but never can a square be a parallelogram. A square is defined as having all four sides the same and all four right angles. A parallelogram has to have two pairs of parallel sides.
are angels having not equal,zize shape and measurement
Some shapes having four equal sides include rhombus, square, diamond, parallelogram with four equal sides, and oblique-angled equilateral parallelogram.
A rectangle cannot be a parallelogram because a parallelogram has opposite sides that are parallel and equal in length, while a rectangle has all angles equal to 90 degrees. Thus, a rectangle is a specific type of parallelogram that has the additional property of having all angles equal to 90 degrees.
It is a rectangle having 4 interior right angles

Parallelogram
A parallelogram.
Well, a rectangle is defined as having two sets of parallel sides and four right angles, a parallelogram is defined as having two sets of parallel sides and two sets of supplementary angles. Therefor, a rectangle is always, by definition, a parallelogram. A parallelogram is not always a rectangle, but it can be.

A paralleogram having 4 congruent sides means it would be a rhombus or a square if it had right angles.
A square has 4 congruent sides and 4 right angles, in addition to having all of the properties of a parallelogram. A kite is not a parallelogram. It has two pairs of consecutive congruent sides, and a pair of congruent opposite angles.
Definition I was taught: "A rectangle is a parallelogram with one right angle" Sounds weird but when you think it out, having one right angle in a parallelogram means the other three must be right as well.
